Method of treating pancreatic cancer

ABSTRACT

The present disclosure describes methods of treating pancreatic cancer and limiting over-expression of oncogenes, activating tumor suppressor genes or regulating signaling proteins in patients comprising administering compounds and pharmaceutical combinations as described herein.

This application claims the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Patent Application No. 62/349,217, filed Jun. 13, 2016, and titled “METHODS OF TREATING PANCREATIC CANCER,” which is incorporated, in its entirety, by this reference.

FIELD

The present disclosure describes methods of treating pancreatic cancer and limiting over-expression of oncogenes, activating tumor suppressor genes or regulating signaling proteins in patients comprising administering CCR2 chemokine inhibitor compounds and pharmaceutical combinations as described herein.

BACKGROUND

Cancer is a significant health problem throughout the world. Although advances have been made in detection and therapy of cancer, no vaccine or other universally successful method for prevention and/or treatment is currently available.

Current therapies, which are generally based on a combination of chemotherapy or surgery and radiation, continue to prove inadequate in many patients.

Located in the upper abdomen in the retroperitoneum, the pancreas is associated intimately with many major structures including the portal vein, stomach, duodenum, common bile duct and the superior mesenteric artery.

Pancreatic cancer is the fifth leading cause of cancer death in the United States. It is more common among men, and men between the ages of 60 and 70 are most at risk. As the tumor grows, the patient's symptoms result from tumor infiltration of surrounding structure causing pain, nausea, vomiting, weight loss and jaundice. The latter condition presents symptoms in no more than one half of the patients.

Once tumor infiltration occurs other structures such as the portal vein become affected and this precludes curative resectioning of the pancreas.

Effective treatment of pancreas cancer is delayed frequently for several months. This delay has profound implications, since metastatic spread to the liver or lymph nodes has been observed at a time of diagnosis in 60% of patients, and this factor diminishes the prospect for long-term survival. Also, the carcinoma of the pancreas is asymptomatic in its early stage. The most common symptoms at later stage are weight loss, abdominal pain, and jaundice. Weight loss, the causes of which are not fully understood, usually is significant. Jaundice occurs if the cancer blocks the common bile duct. By the time the malignant tumor is identified, it often has spread (metastasized) to other parts of the body. The median survival is little more than six months from the time of diagnosis.

Current therapies for this common and difficult-to-treat disease include surgery and/or chemotherapy. Often the tumor cannot be removed by surgery, either because it has invaded vital structures that cannot be removed or because it has spread to distant sites.

Accordingly, there is a need in the art for improved treating primary and metastatic pancreatic cancers.

“Pharmaceutically acceptable salt” refers to a salt which is acceptable for administration to a patient, such as a mammal (e.g., salts having acceptable mammalian safety for a given dosage regime). Such salts can be derived from pharmaceutically acceptable inorganic or organic bases and from pharmaceutically acceptable inorganic or organic acids, depending on the particular substituents found on the compounds described herein. When compounds of the present disclosure contain relatively acidic functionalities, base addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired base, either neat or in a suitable inert solvent. Salts derived from pharmaceutically acceptable inorganic bases include aluminum, ammonium, calcium, copper, ferric, ferrous, lithium, magnesium, manganic, manganous, potassium, sodium, zinc and the like. Salts derived from pharmaceutically-acceptable organic bases include salts of primary, secondary, tertiary and quaternary amines, including substituted amines, cyclic amines, naturally-occurring amines and the like, such as arginine, betaine, caffeine, choline, N,N′-dibenzylethylenediamine, diethylamine, 2-diethylaminoethanol, 2-dimethylaminoethanol, ethanolamine, ethylenediamine, N-ethylmorpholine, N-ethylpiperidine, glucamine, glucosamine, histidine, hydrabamine, isopropylamine, lysine, methylglucamine, morpholine, piperazine, piperidine, polyamine resins, procaine, purines, theobromine, triethylamine, trimethylamine, tripropylamine, tromethamine and the like. When compounds of the present disclosure contain relatively basic functionalities, acid addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired acid, either neat or in a suitable inert solvent. Salts derived from pharmaceutically acceptable acids include acetic, ascorbic, benzenesulfonic, benzoic, camphosulfonic, citric, ethanesulfonic, fumaric, gluconic, glucoronic, glutamic, hippuric, hydrobromic, hydrochloric, isethionic, lactic, lactobionic, maleic, malic, mandelic, methanesulfonic, mucic, naphthalenesulfonic, nicotinic, nitric, pamoic, pantothenic, phosphoric, succinic, sulfuric, tartaric, p-toluenesulfonic and the like.

Also included are salts of amino acids such as arginate and the like, and salts of organic acids like glucuronic or galactunoric acids and the like (see, for example, Berge, S. M. et al, “Pharmaceutical Salts”, J. Pharmaceutical Science, 1977, 66:1-19). Certain specific compounds of the present disclosure contain both basic and acidic functionalities that allow the compounds to be converted into either base or acid addition salts.

The neutral forms of the compounds may be regenerated by contacting the salt with a base or acid and isolating the parent compound in the conventional manner. The parent form of the compound differs from the various salt forms in certain physical properties, such as solubility in polar solvents, but otherwise the salts are equivalent to the parent form of the compound for the purposes of the present disclosure.

“Progressive disease” refers to at least 20% growth in the size of a tumor or spread of a tumor since the beginning of treatment.

“Salt thereof” refers to either a compound formed when the hydrogen of an acid is replaced by a cation, such as a metal cation or an organic cation and the like or a compound formed from a base protonated with a counter-ion. Preferably, the salt is a pharmaceutically-acceptable salt, although this is not required for salts of intermediate compounds which are not intended for administration to a patient.

In addition to salt forms, the present disclosure provides compounds which are in a prodrug form. Prodrugs of the compounds described herein are those compounds that readily undergo chemical changes under physiological conditions to provide the compounds of the present disclosure. Additionally, prodrugs can be converted to the compounds of the present disclosure by chemical or biochemical methods in an ex vivo environment. For example, prodrugs can be slowly converted to the compounds of the present disclosure when placed in a transdermal patch reservoir with a suitable enzyme or chemical reagent.

“Stable disease” refers to cancer that is neither increasing nor decreasing in extent or severity.

“Therapeutically effective amount” refers to an amount sufficient to effect treatment when administered to a patient in need of treatment.

“Treating” or “treatment” as used herein refers to the treating or treatment of a disease or medical condition (such as a viral, bacterial or fungal infection or other infectious diseases, as well as autoimmune or inflammatory conditions) in a patient, such as a mammal (particularly a human or a companion animal) which includes ameliorating the disease or medical condition, i.e., eliminating or causing regression of the disease or medical condition in a patient; suppressing the disease or medical condition, i.e., slowing or arresting the development of the disease or medical condition in a patient; or alleviating the symptoms of the disease or medical condition in a patient.

Certain compounds of the present disclosure can exist in unsolvated forms as well as solvated forms, including hydrated forms. In general, both solvated forms and unsolvated forms are intended to be encompassed within the scope of the present disclosure. Certain compounds of the present disclosure may exist in multiple crystalline or amorphous forms (i.e., as polymorphs). In general, all physical forms are equivalent for the uses contemplated by the present disclosure and are intended to be within the scope of the present disclosure.

It will be apparent to one skilled in the art that certain compounds of the present disclosure may exist in tautomeric forms, all such tautomeric forms of the compounds being within the scope of the disclosure. Certain compounds of the present disclosure possess asymmetric carbon atoms (optical centers) or double bonds; the racemates, diastereomers, geometric isomers and individual isomers (e.g., separate enantiomers) are all intended to be encompassed within the scope of the present disclosure. The compounds of the present disclosure may also contain unnatural proportions of atomic isotopes at one or more of the atoms that constitute such compounds. Unnatural proportions of an isotope may be defined as ranging from the amount found in nature to an amount consisting of 100% of the atom in question. For example, the compounds may incorporate radioactive isotopes, such as for example tritium (³H), iodine-125 (¹²⁵I) or carbon-14 (¹⁴C), or non-radioactive isotopes, such as deuterium (²H) or carbon-13 (¹³C). Such isotopic variations can provide additional utilities to those described elsewhere within this application. For instance, isotopic variants of the compounds of the invention may find additional utility, including but not limited to, as diagnostic and/or imaging reagents, or as cytotoxic/radiotoxic therapeutic agents. Additionally, isotopic variants of the compounds of the invention can have altered pharmacokinetic and pharmacodynamic characteristics which can contribute to enhanced safety, tolerability or efficacy during treatment. All isotopic variations of the compounds of the present invention, whether radioactive or not, are intended to be encompassed within the scope of the present disclosure.

Compounds that Modulate CCR2 Activity

The present disclosure provides compounds that modulate CCR2 activity. Chemokine receptors are integral membrane proteins which interact with an extracellular ligand, such as a chemokine, and mediate a cellular response to the ligand, e.g., chemotaxis, increased intracellular calcium ion concentration, etc. Therefore, modulation of a chemokine receptor function, e.g., interference with a chemokine receptor ligand interaction, will modulate a chemokine receptor mediated response, and treat or prevent a chemokine receptor mediated condition or disease. Modulation of a chemokine receptor function includes both inducement and inhibition of the function. The type of modulation accomplished will depend on the characteristics of the compound, i.e., antagonist or full, partial or inverse agonist.

Without intending to be bound by any particular theory, it is believed that the compounds provided herein interfere with the interaction between a chemokine receptor and one or more cognate ligands. In particular, it is believed that the compounds interfere with the interaction between CCR2 and a CCR2 ligand, such as MCP-1. Compounds contemplated by the disclosure include, but are not limited to, the exemplary compounds provided herein and salts thereof.

The compounds of the disclosure are thought to interfere with inappropriate T-cell trafficking by specifically modulating or inhibiting a chemokine receptor function.

Compositions

Pharmaceutically acceptable compositions can be administered to humans and other animals orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments, or drops), bucally, as an oral or nasal spray, or the like.

Liquid dosage forms for oral administration include, but are not limited to, pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active compound(s), a liquid dosage form may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.

Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid may be incorporated in an injectable product. The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.

In order to prolong the effect of a compound of the disclosure, it is often desirable to slow the absorption of the compound from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the compound then depends upon its rate of dissolution that, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered compound form is accomplished by dissolving or suspending the compound in an oil vehicle. Injectable depot forms are made by forming microencapsule matrices of the compound in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of compound to polymer and the nature of the particular polymer employed, the rate of compound release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the compound in liposomes or microemulsions that are compatible with body tissues.

Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this disclosure with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active compound.

Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or (a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, (b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, (c) humectants such as glycerol, (d) disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, (e) solution retarding agents such as paraffin, (f) absorption accelerators such as quaternary ammonium compounds, (g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, (h) absorbents such as kaolin and bentonite clay, and (i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents.

Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polethylene glycols and the like.

The compounds of the present disclosure or a pharmaceutically acceptable salt thereof may be formulated using nanotechnology. Nanoparticles are attractive for medical purposes based on their unique features, such as their surface to mass ratio being larger than that of other particles, their quantum properties, and their ability to adsorb and carry other compounds. Nanoparticles may have dimensions below 0.1 μm or 100 nm. Alternatively, a pharmaceutical composition may comprise relatively large (size>100 nm) nanoparticles, as needed for loading a sufficient amount of drug onto the particles. In addition, for drug delivery, not only engineered particles may be used as carrier, but also the drug itself may be formulated at a nanoscale, and then function as its own carrier. The composition of the engineered nanoparticles may vary. Source materials may be of biological origin like phospholipids, lipids, lactic acid, dextran, chitosan, or have more chemical characteristics like various polymers, carbon, silica, and metals. Especially in the area of engineered nanoparticles of polymer origin there is a vast area of possibilities for the chemical composition. See, for example, Martins et al., Nanoparticle Drug Delivery Systems: Recent Patents and Applications in Nanomedicine, Recent Patents on Nanomedicine, 2013, 3(2), pp 1-14.

The compounds of the present disclosure or a pharmaceutically acceptable salt thereof may also be in microencapsulated form with one or more excipients as noted above. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings and other coatings well known in the pharmaceutical formulating art. In such solid dosage forms the active compound may be admixed with at least one inert diluent such as sucrose, lactose or starch. Such dosage forms may also comprise, as is normal practice, additional substances other than inert diluents, e.g., tableting lubricants and other tableting aids such a magnesium stearate and microcrystalline cellulose. In the case of capsules, tablets and pills, the dosage forms may also comprise buffering agents. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes.

Dosage forms for topical or transdermal administration of a compound of this disclosure include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants or patches. The active component is admixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives or buffers as may be required. Ophthalmic formulation, eardrops, and eye drops are also contemplated as being within the scope of this disclosure. Additionally, the disclosure contemplates the use of transdermal patches, which have the added advantage of providing controlled delivery of a compound to the body. Such dosage forms are prepared by dissolving or dispensing the compound in the proper medium. Absorption enhancers can also be used to increase the flux of the compound across the skin. The rate can be controlled by either providing a rate controlling membrane or by dispersing the compound in a polymer matrix or gel.

Blood (0.2 mL) was sampled through the jugular vein or cardiac puncture (for terminal point only) at pre-dose, 2, 5, 10, 15, and 30 min, 1, 2, 4, 6, and 8 hours post-dose for i.v. dosing and at pre-dose, 5, 15, and 30 min, 1, 1.5, 2, 4, 6, and 8 hours post-dose for oral dosing. Blood samples were collected into chilled polypropylene tubes containing sodium EDTA as the anticoagulant and plasma was collected through centrifugation (Eppendorf Centrifuge 5417R) at 10,000 rpm and 4° C. for 6 minutes and stored at −20° C. until analysis.

Plasma samples (50 μL) were extracted with 200 μL acetonitrile containing the internal standard on a linear shaker for 10 min and then centrifuged at 3700 g for 10 min at 4° C. (Allegra X-15R centrifuge, Beckman Coulter, Inc., Fullerton, Calif.). 100 μL of the resulting supernatant was transferred into a new plate and mixed with 100 μL 0.1% formic acid in water for LC-MS/MS analysis.

Calibration standard samples were prepared with blank Sprague-Dawley rat plasma, at 5000, 2500, 1000, 500, 100, 50, 20, 10, 4, 2 and 1 ng/mL of compound. Three levels of the standard stock solutions (1000, 100 and 10 ng/mL) were spiked separately into male Sprague-Dawley rat plasma and used as QC samples. Plasma standards and QC samples were treated identically and prepared in parallel with the plasma samples. Extracted samples were analyzed by LC-MS/MS.

Mass spectrometer acquisition and integration were performed with Applied Biosystems-Sciex Analyst software (version 1.4.2). The calibration curve was obtained through a quadratic regression and the calibration range was 2-5000 ng/mL.

Example 3 Pharmacokinetic Parameters of Compound Ib in Beagle Dogs

The pharmacokinetic profile of compound Ib was evaluated in male beagle dogs following intravenous (i.v.) and oral (p.o.) administration. A single dose of compound Ib was dosed intravenously at 0.5 mg/kg and orally at 2 mg/kg. Blood samples were collected at predetermined time points after each dosing and the corresponding plasma samples were analyzed using an LC-MS/MS method. Plasma concentration-time curves were constructed using the plasma concentrations and the corresponding pharmacokinetic parameters were derived by non-compartmental analysis.

Six animals weighing 11.5, 9.9, 9.9, 14.6, 11.1, and 9.8 kg, respectively, were used with Compound Ib dosed intravenously at 0.5 mg/kg (the first 3 animals) and orally at 2 mg/kg (the second 3 animals).

For i.v. dosing, a solution formulation of Compound Ib was prepared in 36.8% water/31.6% propylene glycol/31.6% N,N-dimethyl acetamide at 0.5 mg/mL and each animal received 1 mL/kg. For oral dosing at 2 mg/kg, a solution formulation was prepared in 1% hydroxypropyl methylcellulose at 0.5 mg/mL and each animal received 4 mL/kg.

For dosing, blood (˜1 mL) was drawn at pre-dose and at 5, 15, and 30 min, 1, 2, 4, 8, 12, and 24 hours post-dose. Blood was sampled from the foreleg vein via butterfly catheter and then placed into chilled polypropylene tubes containing K2EDTA as the anticoagulant and kept on ice until centrifugation. Plasma was collected through centrifugation and shipped on dry ice for sample analysis.

Plasma samples (50 μL) were extracted with 200 μL 0.1% formic acid/acetonitrile containing the internal standard on a linear shaker for 10 min and then centrifuged at 3700 g for 10 min at 4° C. (Allegra X-15R centrifuge, Beckman Coulter, Inc., Fullerton, Calif.). 100 μL of the resulting supernatant was transferred into a new plate and mixed with 100 μL 0.1% formic acid in water for LC-MS/MS analysis.
